WAEC GCE 2023 AGRIC PRACTICAL ANSWERS

(1a)

Specimen A:clay

Specimen B:Sand

(1b)

The sandy soil sample B has a lower water retention capacity compared to the clay soil sample A. Sandy soil has larger particles and larger pore spaces, allowing water to drain through more quickly and reducing its water-holding capacity.

(1ci)

Cylinder A:

Percentage of water retained = (Water collected / Water added) x 100

= (10 cm³ / 30 cm³) x 100

= 33.33%

(1cii)

Cylinder B:

Percentage of water retained = (Water collected / Water added) x 100

= (25 cm³ / 30 cm³) x 100

= 83.33%

(1d)

(i) maize

(ii) sunflower

============≠===========================

IV. Feedrack

Uses: for giving livestocks feeds and water

V. Weighing balance

(2b)

The seeds are planted in the farm tool containing the required soil. The set up is placed in the sun with frequent supply of adequate water. After leaving for few weeks,the seeds starts to germinate and it’s then transplanted to the field properly.

========================================

(3a)

Area =30,000

Spacing= 1*0.5=0.5m²

(3b)

Germination 90% =90%

Total population =50000/1 = 50000

Expected plant population =90/100*50000 =45,0000
